SPECIFICATION forming part of Letterslatent No. 566,609, dated August25, 1896.

Application filed June 23, 1896. Serial No. 596,636. (No modell) To allwhom it may concern:

Be it known that I, CLARENCE liv-'ALTER NASH, cf Union Bridge, in thecounty of Carroll and State of Illaryland, have invented a new anduseful Improvement in Lubricators, of which the following is aspecification.

The object of my invention is to provide a simple, practical, andefficient lubricator, or oil-cup, of that class in which the feeding ofoil is effected by the intermittent opening of a valve operatedautomatically by the momentum or centrifugal action of the valve whenmounted upon the wrist-pin of a crank or other revolving partsusceptible of impart ing such action to the valve.

It consists in the peculiar construction and arrangement of the partsdesigned with reference to simplicity, ease of construction, andconvenient application and adjustment, which I will now proceed to fullydescribe with reference to the drawings, in which- Figure l is avertical central section. of the lubrieator; Fig. 2,ahorizontal sectionthrough line 2 L of Fig. l, and Fig. 3 a side view of the valve-casingand its adjusting devices removed from the oil-cup.

In the drawings, represents the oil-cup, which has a screw-threaded capC for closing in the top of the same.

A is the valve-casing, which stands centrally within the oil-cup andserves the double purpose of holding the alve and fastening the oil-cupdown to the wrist-piu or other part upon which it is mounted. For thispurpose the oil-cup is made with a central hole in its bottom surroundedby a recess c, having angular walls adapted to receive acorrcspondii'igly-shaped boss or projection A', formed on thevalve-casing, and from which t-here protrudes through the central holein the bottoni of the oil-cup a tubular extension A2, having an externalscrew-thread adapte-d to be turned into a screw-threaded hole in thewrist-pin or other support upon which it is mounted. This angular recessc, receiving the boss A of the valve-casing, permits both these parts tobe placed together and then screwed into their support without the useof a special wrench fitting inside the oil-cup, as the latter, throughits recess c, acts as a wrench upon the valve-casing and threaded tubeA2.

Just above the boss A' the valve-casing has four more or less lateralholes a, which communieate with the tubular extension A2, through whichoil is admitted to the point of lubrication on the wrist-pin. 'Withinthe valve-casing A there is an adjustable sleeve D, screw-threaded onits exterior and meshing with an interior screw-thre ad of thevalvecasing A. This sleeve has its upper end fashioned into a nut d,which has a nick d2 in its upper surface, by which it may be rotated bya special forni of screw-driver, or which may be made square orhexagonal to receive a wrench, or it may have a butteriiy-nut, or anyother convenient means maybe provided for turning it. Centrally throughthis sleeve and nut there slides the valve-stem B, carrying the conicalvalve h and a reduced stem Z1 below it, all made in one piece. Thisvalvestem projects through and rises slightly above the nut d and isgrooved peripherally or formed with a knob or head b2, by which it mayhe seized with the fingers and pulled up in case the valve gets stuck inits seat in the boss A' below. The sleeve D extends a little below thevalve-casing A and forms an adjustable stop-shoulder d, against whichthe upper surface of the valve strikes as it rises to limit itsmovement.

The action of this oil-feeder is as follows: Then mounted upon thewrist-pin of a wheel, a revolving crank, or other similar part of amachine, on the upper half of the revolution the valve-stem B, withvalve b, rises from centrifugal action of its own momentum and a fewdrops of oil pass through the holes a to the narrow annular spacebetween the valve-stein b and the screw-threaded tubular extension A',and pass to the point to be lubricated. -If it is desired to increasethe feed of oil, the sleeve D is raised slightly by turning up the nutd, and the valve l) then rises a little higher If the feed of oil is tobe reduced, the sleeve D is screwed down. In such adjustment it is onlynecessary to unscrew the cap C' of the oil-cup, and the parts are theneasily accessible, the protrusion of the valve-stem B above the nut dpermitting it to be seized and lifted in a convenient manner whenever itbecomes stuck or gummed, and also allowing a free lubrication of theIOC) stem throughout its length, so as to insure its sensitive action. Y

I am. aware that valves have been arranged within oil-cups to rise fromtheir own momentum in revolving about the crank center, and l make nobroad claim to this, but only to the peculiar' constru ction andarrangement of parts which make a very efficient, convenient, andpractical lubricator.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isv l. The combination of an inclosing oil-cupand its detachable cap; of a valve-casing A fixed within the same andhaving lateral openings a and an interior screw-thread eX- tendingi'roin said openings to the upper end oi said casing, an adj ustablestop for the top of the valve consisting of a sleeve D arranged withinthe casing and screw-threaded eX- teriorly its entire length to engagewith the screw-threads of the casing, and having a turning nut at itsupper end with an opening extending entirely through the same, and avalve-stein extending entirely through this sleeve and projecting above`the top of the nut and carrying a valve below playing between its seatin the casing and the superposed lower end of the adjustable stop-sleevesubstantially as and `for the purpose dej scribed.

2. The combination of an oil-cup having a locking-recess in its bottom;of an automatically-moving valve and a casing for the same having ascrew-threaded projection extending through the bottom of the oil-cupand a boss or projection iitting within the recess in the bottom of theoil-cup to lock these two parts together for rotary action in screwingon the oil-cup substantially as and for the purpose described.

3. The combination of the oil-cup having recess c in its bottom, and adetachable cap, the valve-casing A with locking-boss A', litting inrecess c and locked to the oil-cup thereby, said valve-casing havingalso screwthreaded tubular extension A2 and inletholes a, the adjustablescrew-sleeve D with perforated nut d, and the concentric valvestem Brising through the sleeve and nut and having a valve b and reducedextension b1 substantially as and for the purpose described.
